I'm loving my XE (now my 3rd HTC) just as it is, plus I'd be too scared of turning it into a brick. I guess only you can decide if it's worth it.... what would it actually give you that you don't have now?

I had the 1.18.0000 HBoot version before i updated to ICS..It then changed to 1.29.0000..after i finished my phone warranty..I officially unlocked my bootloader with the HTCdev.com and the ultimately rooted my phone with the juopnutbear S-Off utility...
